4'. Claims.

In the usual construction, of gas meters, the case is formed in two parts, the lower part forming the diaphragm space and the upper part forming a chamber in which are` arranged the valves and yworking partsMThesdial isoperatedlbly meansl of a shaft from the Working parts, the shaft4 extending througha stufng box. Withthis structure all the workingA parts are subjected to the gas and the corrodingy effects thereof. The dial is necessarily mounted on the outside of the case so lthat the yvalve-chamber may be closed and the Valve partsvare usually-mounted in the walls of the-meterjcase itself.A With the present invention We have separated the upper 1i Chamber-forming an; upperportion for the tangent and immedizfitelyk connected parts in this chamber and sealing a chamber immediately be-4 low, this in which are arranged the valves.A With thisconstruction'it is possible to mountthe Works ,20 ing parts on the plate sealing the valve portion of the chamber and inasmuch as the upper chamberis free from gasit is possible to mount the dial on this same plate. In consequence the entire Working parts, outside of the valves and flag arms may be mounted on this single plate,

thus making a unit assembly. This small plate can be more readily handled and the parts thus more rapidly assembled and inasmuch as the plate and the parts carried thereby may be re- C.t0 moved as a unit this also facilitates the servicing of the meter. Preferably also this sealing plate has small openings by means of which the links from the crank post can be connected to the valves and adjusted so as to properly position -...t5 the valves. Other features and details kof the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as 'fol- ,40 lowsz- Fig. 1 shows an elevation of a meter, a part being broken away to a section on the line 1--1 in Fig. 2.

1 marks the diaphragm portion ofthe case,

and 2 the ,upper portion of the case. These two portions are sealed with agasket 3. An inlet passage 4 is arranged in the upper portion. It

meter with the tp has an off-set 4a giving clearance for the flag arm. The passage 4 leads throughan opening 5 in the lower portion. The opening 5 leads to a filter receptacle 6 over which is arranged a screen 7. The filter material is preferably horse hair. 6,9..y The gas passes from lter receptacle through the screen into a valve compartment 8, passing from the valve compartment through a port 9 in a valve seat 10, by a passage `11 to a diaphragm 12, returningy through a passage 13, port 14, valve 15, port 16, passage 17, to a discharge opening 18 in the upper portion ofthe meter. l .l

A sealing plate 19 is arranged over thetop of the valve compartment separatingthe valve compartment from theftangent chamber. The 79. plate is secured by screws 19a arranged around l the edge of the plate and the joint between the plate and the upper face of the meter is sealed by theggasket 3. A ,Y

.A crank post, 20 has its lower end journaled 'is ,ina bearing socket 21 in the bottom wall ofthe valve/fcompartment.v A crankV 22 Yis arrang'ed in the valve compartment and connecting rods 23 extend from the crank to pins 24 on the valves.

The crank post extends through a stufng box 25 so l on the sealing plate 19 into the tangent chamber and through a bearing in a supporting arm 26, this arm being supported by a bracket 2'7 secured on the sealing plate 19. A tangent 28is xed on the upper end of the crank post and is provided with the usual tangent post 29. Links 30 extend from the tangent post to flag arms 31. The flag arms 31 are fixed on the flag-staves 32, the flag-staves extending through stuing boxes 33. The staff has the usual bail, or crank connection 34 which is connected by arms 35 with the diaphragm, it being understood that the valves, flag arms, staves and similar mechanisms are duplicated at opposite sides of the meter in the usual manner.

`'I'fhe sealing plate is preferably provided with small service openings 36 which may be sealed 'by a cover plate 3'7, the cover plate being provided with a gasket 38. l

It will be noted that the crank shaft 20 having 100 the crank 22 and tangent 28 is mounted on the sealing plate. In fact the Working parts,except the valves and the flag arms with their links are all assembled on the sealing plate and that the vvalves are put in place in their usual manner y and the sealing plate secured in place. After the sealing plate is in place the connecting rods 23 may be positioned on the pins 24 by access to the connecting rods through the openings 36. The connecting rods are provided with the usual loops l11.0

39 which may be nicely adjusted as to length. After they are in place the cover plate 37 is put in place.

A register 40 is secured on a bracket 41 on the sealing plate and is driven by a shaft 42 having a gear 43 engaging a worm 44 on the crank post. Inasmuch as this upper chamber has no gas all that is necessary is to provide an opening in the case exposing the dial and the dial thus may be completely mounted and connected up on the sealing plate before these parts are put in place. It will be seen, therefore, that the dial mechanism as well as the crank mechanism with its shaft is mounted on the sealing plate. Thus the convenience of the structure is very much enhanced, inasmuch as these working parts may be assembled as a unit and in servicing the sealing plate of a defective unit may be removed and a new unit inserted.

While we have shown a filter arranged directly in the case this per se does not form any part of the present invention.

What we claim as new is:-

1. In a gas meter, the combination of a case having a diaphragm compartment, a valve compartment and a chamber; a plate separating the valve compartment and the chamber; means removable at ordinary atmospheric temperature securing the plate in place; a crank post mounted on the plate; a register mounted on the plate; a driving connection between the register and post; a valve in the valve compartment driven from the post; and means driven by the diav phragm actuating the crank post.

2. In a gas meter, the combination of a case having a diaphragm compartment, a Valve compartment, and a chamber; a diaphragm in the diaphragm compartment; a valve in the Valve compartment; a flag-staff extending from the diaphragm compartment to the chamber; means in, said diaphragm compartment and connecting said flag staff to said diaphragm so that said flag staff may be actuated by said diaphragm; a flag arm on the staff a crank post; a removable plate between the valve compartment and the chamber and on which the post is mounted; a tangent on the crank post; a connection between the flag arm and the tangent; a connection between the crank post and the valve; a registeringmechanism mounted on the plate; and a connection between the registering mechanism and the crank post.

3. In a gas meter, the combination of a case having a diaphragm compartment, a valve compartment, and a chamber; a diaphragm in the diaphragm compartment; a valve in the valve compartment; a flag-staff extending from the diaphragm compartment to the chamber; means in said diaphragm compartment and connecting said flag staff to said diaphragm so that said flag stati may be actuated by said diaphragm; a flag arm on the staff ya crank post; a removable plate between the valve compartment and the chamber and on which the post is mounted; a tangent on the crank post; a connection between the flag arm and the tangent; a connection between the crank post and the Valve; -a registering mechanism mounted on the plate; and a connection between the registering mechanism and the crank post, said plate having an opening giving access through the plate to the valve compartment.

4. In a gas meter, the combination of a register; a crank post having a crank; means actuated by the crank post and actuating the register; a valve; a connection between the valve and the crank actuating the valve; a diaphragm.; a driving connection between the postand the diaphragm; and a mounting for the'post, register and means, said mounting being removable and forming with the register, post and means a unit assembly.
